<h2>Detailed Description</h2>
|
|
<p>The QAxScript class provides a wrapper around script code.</p>
|
|
<p>Every instance of the QAxScript class represents a piece of scripting code in a particular scripting language. The code is loaded into the script engine using <a href="qaxscript.html#load">load</a>(). Functions declared in the code can be called using <a href="qaxscript.html#call">call</a>().</p>
|
|
<p>The script provides <a href="qaxscript.html#scriptEngine">scriptEngine</a>() provides feedback to the application through signals. The most important signal is the <a href="qaxscript.html#error">error</a>() signal. Direct access to the <a href="qaxscriptengine.html">QAxScriptEngine</a> is provided through the <a href="qaxscript.html#scriptEngine">scriptEngine</a>() function.</p>
|
|
<p><b>Warning:</b> This class is not available with the bcc5.5 and MingW compilers.</p>
